Abstract: Objective To investigate the effects of the intellegent CO2 laser assisted Fisch stapedotomy with artificial stape prostheses in the treatment of otosclerosis.Methods A total of 28 patients with otosclerosis who had undergone the intellegent CO2 laser assisted Fisch stapedotomy with artificial stape prostheses were retrospectively e-valuated.The intellegent CO2 lasersare was used to vaporize stapedius tendon,posterior crus of stapes,and most importantly perforate stapes footplate.Bone and air conduction thresholds were determined at 0 .5 ,1 ,2 ,and 4 kHz preoperatively and 6 months postoperatively in all patients.Results No sustained vertigo or sensorineural hearing loss occurred postoperatively.There were no statistically significant differences between preoperative and postopera-tive average bone conduction thresholds.Preoperative and postoperative air bone gap were 30.38(23.13,39.38)dB HL,9.75(8.25,10)dB respectively and the postoperative results were significantly different from the preopera-tive.Conclusion The intellegent CO2 laser can be used safely in stapes footplate surgery and is well suited for trea-ting otosclerosis.
